본 발명의 방법은, 섬유화 가능영역이나 또는 소정의 섬유화 가능영역으로 압출된 액정수지 복합재를 함유한 수지 혼합물의 압출 또는 사출성형 수단에 의해, 섬유화 가능영역이나 소정의 섬유화 가능영역이내에서의 혼합비로 액정수지 섬유에 의해 수지복합체가 보강되는 것이 특징이다.The method of the present invention provides a mixing ratio within the fiberizable area or the predetermined fiberizable area by means of extrusion or injection molding means of the resin mixture containing the fiberizable area or the liquid crystal resin composite extruded into the predetermined fiberizable area. The resin composite is reinforced by liquid crystal resin fibers.
